Vimercati Shareholder Plans to Exercise Pre-Emptive Right in Connection With Stoneridge's Offer to Acquire Vimercati

WARREN, Ohio, April 22 -- Stoneridge, Inc. announced today that it has been informed that a shareholder of Vimercati S.p.A. intends to exercise a pre-emptive right to acquire the remaining outstanding shares of Vimercati, subject to the same terms and conditions set forth in Stoneridge's agreement to acquire Vimercati. The shareholder has given notice of his intent to the other Vimercati shareholders.

If this shareholder is successful in acquiring the shares, Stoneridge's agreement to acquire Vimercati will be terminated. If the shareholder fails in his bid to acquire Vimercati, the Company may still complete the acquisition of Vimercati, subject to customary closing conditions. However, at this time, because of the exercise of the pre-emptive right, the Company does not expect to close the acquisition.

On March 29, 2005, Stoneridge announced its agreement to acquire Vimercati, an Italian full-service switch products supplier for the automotive industry. Because it was known that the shareholder had the option to exercise his pre-emptive right, Stoneridge negotiated protective provisions designed to provide the Company with a termination fee of 250,000 euro in the event the Company did not acquire Vimercati as a result of the shareholder's exercise of the pre-emptive right.
